what would be the mass required to keep an object with a mass of 250kg orbiting at a constant distance of 100km with a linear velocity of 100m/s?

the linear speed of an orbiting body is given by the equation sqrt(GM/2r) where M is the mass of the attracting body, G is the gravitational constant and r is the distance between the two bodies' centres ...

Given that p≥ -1 , prove by induction that, for all integers n≥1 , (1+p)^k ≥ 1+k*p.

First of all, we need to show that the statement is true for the base case n=1. For this case the expression becomes: 1+p≥1+p, which is clearly true as both sides are equal and hence solve the inequality....

How would I differentiate a function such as f(x)=x^3(e^(2x))?

Here, f(x)=x³e^2xis a function consisting of two functions multiplied together, so we need to use the product rule. The product rule is as follows: where f(x)=u(x)v(x), f'(x)=u(x)v'(...
